Another object. is so to ar is provided; a plurality of lacingr mechanisms hav- . ihg, a series of lacing needles for inserting a separately fastened lacing within each pair of aligned eyelets in a folded shoe upper, rI'he .15 folded upper is applied to the series of needles which act. to carry the upper into operating posi tion in the machine, and which thereafter are reciprocated and alternately moved laterally ?rst in one direction and then, in the other to, carry 20 range a lacing maQhine for operation upon up~ pers- having curved rows of eyelets, that a single set, of adjustments. only is necessary for success lE-ul operation on a particular style of shoe, the machine being capable oi operating upon a full range of shoe sizes having the same style Without other adjustment. 7 With the above objects in view, an important feature of the present invention consists in the aseparate Strand of cord through each pair of provision, in a machine having a series of lacing aligned eyeletsjto. arm an individual lacing, ,TO devices. operating to pass a series of individual enable the laced upper to be opened out for ap lacings through the aligned eyelets of a folded plication to a last, the lacings are formed With. a shoe upper, of quickly adjustable means for pro predetermined amount of slack. To form, the 135 duc-i-ng slack in each- lacing in an amount differ slack in the lacings, each needle during’ its, lateral ing from one lacing’ toanother and departing movement carries the lacing cord across a cord from a uniform difference between successive lac measuring ?nger which is'suitably spaced from ings to the extent required by the curvatures in the upper. the‘ eyelet rows.

When applied to a to: produce slack in each lacing progressively in last, the eyeletted edges of the upper may extend creasing in amount from one lacing to another in parallel relation to each or with varying de and, separately adjustable to produce slack in grees of angular divergence from the toe end‘ of each lacing in an amount departing from a uni the edges towards the ankle opening in the form progressive difference between successive upper, depending on the style of last. To enable this angular divergence to be changed, the meas uring ?ngers are spaced from the upper to pro vide uniformly and progressively increasing lengths in successive lacings from theitoe end of the eyelettededges towards thev ‘ankle opening. With di?erent stylesof‘ lasts, the locations of the measuring ?ngers are adjusted by changing the positions of the ends of a rod against which the measuring ?ngers are forced by the action of lacings. These. and other features consist in the: con structions, combinations and arrangements of parts hereinafter described and claimed.
